Your county treasurer can provide a copy of your property tax statement and answer any questions you may have about the statement. The county treasurer mails these statements to property owners by March 31 each year. Tax payments are due to your county on May 15 and October 15, for most properties. For contact information, check your local phone book or see County Websites on Minnesota.gov.
You can still file for the refund. You have one year from the due date to file and claim the refund. However, if you file the return more than one year after the due date, you will not receive a refund.
